SPECIFICATION forming part of Letters Patent No. 281,291, dated July 17,1883.

Application filed October 19,1882. (No model) T0 40% whom it mayconcern.-

Be it known that I, HENRY S. OHL, Jiz, of the city of Phil adelphia,inthe county of Philadelphia and State of Pennsylvania, have inventedcertain new and useful Improvements in Locks or Latches; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, and of its mode or manner ofoperation, reference being had to the accompanying drawings, making partof this specification.

My invention relates to an improvement in spring-latches adapted to beused for car'windows and kindred purposes; and it consists in such anarrangement of the parts that the bolt will be withdrawn when the knobis lifted up, and also when the knob is pulled down, thus making a latchin which the knob will perform the function of a knob for withdrawingthe bolt, and at the same time and by the same motion will lift or lowerthe sash, as desired.

In the drawings, Figure 1 shows one method of applying my latch to awindowsash. Fig. 2 is a front view of the latch-case open, showing thedifferent parts in position when the latch is out. Fig. 3 is a side viewof the latch, showing the outer case cut away in section, and disclosingthe interior parts. Fig. i is an inside top view of the slide 6, showingits various parts more clearly. Fig. 5 is a side view of the slide 6.Fig. 6 is a front view of the latch-case with the inserted partsremoved. Fig. '7 is an end view of the dog or pawl 01. Fig. 8 is abottom view of the same pawl d.

9 is an end view of the bolt '1) from the projecting end. Fig. 10 is aside view of the bolt 12, and Fig. 11 is an end view of the bolt 1) fromthe inclosed end.

Similar letters of reference indicate like parts in all the drawings.

A is the latch-case, provided with suitable bosses, a, for the lid B torest upon.

B is the lid or other part of the case A, and it is pierced withsuitable holes for screws to hold it to the case, and also with holescorresponding to the holes m, for screws to pass through the case andlid A B to secure the latch-case to sash, when desired.

2) is the bolt running in a'snitable channel,

made in the example of my invention shown in the drawings by the groovesor studs (2 0, attached to the case A, and similar studs, 0, attached tothe inner side of the lid B, and this bolt 1) may have the underside, orpart which moves over the slide e, somewhat cut away, as indicated inFig. 11.

a, a are pintles on which turn the dogs or pawls d d, which have cutaway a portion of that part of the under side of the arm which movesover the slide (2, as shown in Figs. 7 and 8. The portions of thesepawls or dogs which grasp and move the bolt may be cut away concave tosecure better engagement, as shown in Fig. 7, a

e is a slide having pins ff at each end, between which play the engagingends of the arms of the dogs (I d, and provided on its side with theprojections 0 0, which are of a suitable size to reach the end of thelatch-case, and serve to steady the slide in its movements; and p is alug which fits into the slot 9, and guides the movement of the slide 6,and limits the movements upward and downward of the slide.

9 is a slot in the side A of the ease, in which the lug'p moves, andinto this lug is secured the knob 71, by means of which the slide 0 andthe bolt b are actuated.

i is a suitable spring to throw out the bolt 1), and it is secured inposition in any convenient manner.

It is a projection on the bolt 7), which limits its movement outward,and against this the spring a; presses, as shown in the drawings.

Z is a similar projection for the engaging face of the pawls d d topress against to draw back the bolt when desired. These projections Z: Zmay be made of suitable size to move easily between the sides A B of thecase, as shown in the drawings, and thereby the bolt is steadied in itsmovements.

The operation is as follows: When it is desired to raise the sash, theknob h is lifted, drawing up the slide 6. This raises the end of thepawl d between the pins f f and forces the other end of the pawl backand against the projection Z on the bolt 1), drawing back the bolt andlifting the sash. Upon letting go the knob the spring 6 throws out thebolt into a suitable recess provided for it on the side of thewindow-frame. When it is desired to lower the sash,the knob h is pulleddown, which draws down the slide 0. This draws down the end of the pawld between the pins f f on the slide e and forces the other end of thepawl back and against the projection l on the bolt, drawing back thebolt and lowering the sash.

For fastening the lid B to the case, sma11 screws maybe introducedthrough it and into the pintles a a,- if desired.

Instead of having a straight spring to throw out the bolt,a coiledspring may be placed over the bolt 1), if desired, one end pressingagainst the projection 76 of the bolt and the other end resting againstthe stud c of the lock-case A.

When it is desired to raise the sash it will be well to press down uponthe sash until the bolt is withdrawn from its recess, so that the Ipressure upward on the knob h will not press the end of the bolt againstthe upper side of the recess in the window-case with such force that itwill be difficult to withdraw it, and so the sash may be pressed upward,until the bolt is withdrawn, when drawing down the knob h,

to engage with the bolt and withdraw the same when the lift is forcedupward to raise the sash, and also to engage with and withdraw the boltwhen the lift is forced downward to lower the sash, substantially asdescribed.
